Stellar velocity field (left) with H₂ 1-0 S(1) velocity contours and H₂ 1-0 S(1) velocity map with contours (right). The contour levels are  − 75, − 50, − 30, − 10,0,10,30,50,75 km s^-1. The color bar describes the H₂ and stellar velocity in km s^-1. On the right panel, the red circle represents the 3σ uncertainty for the center defined by Müller-Sánchez et al. (2010). The plus sign is the center of this circle, and the kinematic center. The diamond is TH2, the radio peak. The triangle is X-1, the X-ray peak. The square is the point of highest symmetry.
